1788 Connecticut Copper. Miller 4.1-K, W-4430. Rarity-4+. Mailed Bust Right. AU-58+ (PCGS).
125.6 grains. An exemplary piece with lovely tan color and as much intact mint luster as we have seen on a Miller 4.1-K. Double struck with just a slight offset between strikes, something commonly seen on this variety, with a shift visible on many of the letters, date, and seated figure. Obverse nicely centered, the reverse a little off to 3 o'clock with weakness at ET LIB as a result. While there are a number of nice examples of this variety known, many with the same choice color as here, this is noticeably superior to almost all in surface quality, luster, and overall strike. There were three nice examples in Partrick, including one graded NGC MS-62 Brown, but that piece was not as well struck and had areas of planchet roughness. This is the single finest graded for the variety at PCGS and one of two AU-58+ for the Mailed Bust Right type with five graded higher.
PCGS# 687252.
